10. The electronic device of claim 1, wherein the at least one processor is configured to, in the reduced state, identify a third edge area of the flexible display disposed in a bottom direction from a center of the electronic device as the first input area, and in the expanded state, identify the third edge area as the second input area.

11. A method for controlling an input area for expansion or reduction of a display in an electronic device, the method comprising: identifying a reduced state in which a flexible display is slid in a reduction direction or an expanded state in which the flexible display is slid in an expansion direction, wherein the expansion direction is opposite to the reduction direction; in the reduced state, identifying a first edge area of the flexible display disposed in the reduction direction from a center of the flexible display as a first input area and performing control such that the flexible display enters the expanded state, based on reception of a first input through the first input area; and in the expanded state, identifying a second edge area of the flexible display disposed in the expansion direction from the center of the flexible display as a second input area and performing control such that the flexible display enters the reduced state, based on reception of a second input through the second input area.

12. The method of claim 11, further comprising: identifying a distance at which the flexible display is slid in the reduction direction or the expansion direction, by using a magnet disposed in a first housing of the electronic device, and at least one hall sensor disposed in a second housing of the electronic device to sense a magnetic field generated by the magnet.

13. The method of claim 11, wherein each of the first input and the second input comprises one of a swipe input after single long touch, a multi-swipe input, or a multi-touch input.

14. The method of claim 11, further comprising: displaying, on at least a portion of the first edge area, first information indicating that the first edge area is an expansion request input area or displaying, on at least a portion of the second edge area, second information indicating that the second edge area is a reduction request input area.

15. The method of claim 14, further comprising: designating a display position, size, color, or type of the first information or the second information, based on a user input.

16. The method of claim 11, further comprising: identifying whether the expanded state is a partially expanded state or a fully expanded state.

17. The method of claim 11, further comprising: when the first input is received through the first input area in the reduced state, identifying whether the first input is a partial expansion request input or a full expansion request input, based on a designated condition; and performing control such that the flexible display enters a partially expanded state, based on identification of the partial expansion request input or performing control such that the flexible display enters a fully expanded state, based on identification of the full expansion request input.

18. The method of claim 17, wherein the designated condition comprises one of a type of the first input, a type of an application to be executed upon the first input, a type of a file to be executed upon the first input, or a user selection input using a pop-up menu.

19.
